Photoshop: How can I get get Corel's KPT Filters to work in Photoshop CS5?

When there is finally a solution for the installation of the KPT filters collections? I need this filter urgently and use Photoshop CS5. It can't be that the costumers must throw away all of his past purchases of filters just because Adobe is not able, at short notice to take corrective action. I expect in such an expensive program that NOW is an update, if such a problem! Otherwise, it was the last time that I spend many of €'s in a program where I have to throw away all old plugins, because they don't work no longer in the new versions of Photoshop. The CS5 version is now over 1 year on the market, but as a developer should be able to upgrade at this time - to bring out so that the customers are happy again - and which fixes this problem.
If Adobe not quickly find a solution, I will NEVER buy Photoshop again! I see this not imagine that I mean expensive filter collections throw in the garbage because Adobe says, you'd need no more! I'm as an Adobe customer absolutely angry and don't accept such a policy!

No they don't work in 32-Bit, because I tried to install them to 32-Bit (in 64-Bit no filter works in Photoshop!) - please look at my screens. If you think, they work in 32-Bit, tell me please how????
I'm angry about Adobe, because it's not a problem of Corel - in the past versions of Photoshop all my filters are working, only in the new version of CS 5 not - why??? Should I throw all my old filters away because I use the new Photoshop? You also know, that Corel wouldn't upgrade new KPT Filters - why you say something like this? So the graphic software should develope software which supports older filters - we are talking about graphic software and not any other software. And for this expensive investment, I can expect a proper functioning of filters of any kind. Such a thing is certainly unacceptable for me! Sorry...

So the plugins show up in the UI? That's good. But then they don't load - that's a bug in the plugin, or some sort of install problem (KPT plugins rely on some libraries that install with them).

Photoshop is compatible with older plugins, and most older plugins still work in Photoshop 32 bit. But if the plugin authors have not updated them for recent OS versions, or 64 bit addressing - then they aren't always going to work. We go to great lengths to make sure that Photoshop is compatible with existing plugins, but we can't update third party code, nor can we debug it to see why it's breaking.

I'm sorry you're having problems, but your problem is with plugins written by Corel, not Adobe. Corel owns the KPT plugins, they are the only party that can update them. If you want the KPT plugins to work in modern versions of Photoshop and modern OSes, please ask Corel to update their plugins.

I think, that could't be a problem of Corel, because the long time before, all the filters works with the Photoshop Versions. Only the new Version doesn't accept these filters? Corel doesn't change something at these filters, which are no longer on the market, but Adobe change the program! So I think, this is a problem at Adobe (because Adobe is changing something at Photoshop, that this filters doesn't work any longer). I'm really very angry about this, because I can't use all my old KPT Filters, which I purchased from Amazon and Pearl Online shops! I'm certainly doesn't buy a new Photohop in the future because I don't want to support such a policy! To me it does not help, if any (Adobe and Corel) pushes the error on the other manufacturers, why no update is made ​​to this problem.

I understand your frustration (the KPT filters were written by friends of mine, and I used them for many years). But the problem is in Corel's code, and only Corel can change their code.

This is not Adobe's problem, and I highly doubt if an update to Photoshop could fix bugs in Corel's code. We don't know why they don't work while thousands of other plugins (some older than KPT) still work without a problem. Small changes in the application loading can cause problems if the plugin author made mistakes in writing the plugin. This happens with every release of Photoshop - some plugin breaks and we don't know why. When we talk to the plugin authors, they update their code and usually find a bug or bad assumption that was preventing it from working -- really unrelated to the changes in the host application. We do go out of our way to keep old plugins working, but we don't have the code for third party plugins, and can't fix their bugs ourselves.

If you want the KPT filters to work, all you can do is ask Corel to update their code. There is nothing Adobe can do about it, and certainly no reason to blame Adobe for the bugs in Corel's product.

I have 4 versions of photoshop on Windows. 7, CS2, CS3 and CS6. I have all versions of KPT plugins to include version 3. I installed all KPT into the version 7 plugin folder. ( I am running 32 bit ). Then I point all CS app's to that folder. The only plugin having problems is KPT 3. The workaround for that problem is to undock the layer panel from the CS application. In other words drag the layer panel from the 'well' on the right hand side so that it is floating within the apps' window by itself. This will allow the plugin to work and close once rendering has occurred. I also have all versions of Elements to include Premiere ( junk ) and began having problems with KPT 3 in the release of Elements 4. The work around worked since then.

I'm very sorry, because I didn't agree with you with your reasoning. As these older filter (for which, as you know certainly, was no recent updates and always will be) in earlier versions of Photoshop run correctly, I assume that Adobe changed something in the new version at the basic, that this filter is not anymore in the latest version work. The question is, justify this change by Adobe that you now have to throw all the old filters in the trash and are no longer usable?
Your advice to contact Corel (knowing full well that Corel will do anything and is unavailable), in your opinion is of course easy - but fixes not user problems and is therefore contra productive. Since you are one of the co-developer of Photoshop, you should be based on reality and not what Adobe means to keep fit. In a graphics program in this financial magnitude is about that all the associated add-ons and filters are matched and then will work also.
Then you need to develop something, where filters are working properly (something you can test in the development before). You can't just throw away all the years the older addons and plugins, just because a new version of graphic software comes on the market - Do you find this right?
You know just like me - that there will be for the KPT filters by Corel no more updates ... So, what will become of this nonsense? I can honestly makes no sense why I contact to Corel for old filter (which are no longer on the market) and their new updates - especially as the filter in the previous Photoshop versions always worked fine - that Adobe has changed somewhat, which is no longer mates with these filters ... So should you or Adobe as co-developer to think about what you changed and whether these changes are really necessary and useful for a graphics program - I mean NO! As I said, we are not talking about a 08-15 product, but by a program that now costs a lot more than 1000 € and there is this a "No Go"!

I know how the code works in Photoshop and in plugins. I know that Photoshop did nothing to directly disable the KPT plugins, and I know that Corel has not update their plugins in quite some time. That means that some minor change in Photoshop exposed an existing bug in the KPT plugins (and they do have many bugs). Most likely the KPT plugins made a bad assumption about some function in Photoshop that isn't part of the plugins API and doesn't affect other plugins, or maybe they misunderstood part of the API, or maybe they made bad assumptions about the OS DLL loading system, or maybe they depended on a deprecated OS API, or... well, only Corel knows what the bugs are in their code.

If Adobe changed something that broke the KPT plugins: it was unintentional or a security requirement. Again, plugins break for many reasons -- which are usually bugs in the plugins that have nothing directly to do with changes in the application. But since we do not have the source code to those plugins, we can't know why they are breaking. When we work with third party developers to debug plugin bugs like this, the developer usually finds that there was a real bug in the plugin and it had nothing to do with Photoshop directly.

Adobes goes to extreme lengths to make sure that older plugins continue to work with newer versions of Photoshop. We test all the available third party plugins that we can, and we spend quite a bit of time trying to keep them working (at the API level, sometimes with workarounds to known issues, and a lot of time spent working with third party developers). If we could make the KPT plugins work, we would. But we can't.

Corel is still in business, they own the code to the KPT plugins, and until such time as they sell that code (and IP) to someone else they are the only ones who could possibly update the KPT plugins and fix the bugs in the KPT plugins.

Why are you so resistant to contacting Corel? You don't know that they won't update them (unless you work there). They still sell the plugins (http://www.corel.com/corel/product/in...) - so contact Corel and ask them to fix the bugs in the plugins.

Why are you trying to blame a party who has nothing to do with the bugs in the KPT plugins, and can't do anything about the bugs in the KPT plugins? Adobe didn't "throw away" old plugins, but works hard to keep them working.

You can also download or purchase KPT from AutoFX as a bundle. They will assist in the 'debugging' of KPT plugins in Photoshop. They too, update plugins to consistently work in Newer versions of PS. If only Andromeda and NIK would do the same and write code to allow auto-updates.

I turn to Adobe, because I can't reach anyone at Corel. A contact by phone, across a forum and via email doesn't work (like the KPT filters). I can't reach the whole company Corel! That's the good customer service of Corel! And someone has to take on this problem after all, because by itself solves nothing!
The link to Corel I have previously tried, but please try to Corel by phone or via the forums Community - hopeless!

I quit investing my dough in Corel when they purchased Paint Shop Pro from Jasc. They overhauled the whole program and made it a thick piece of junk. Since then KPT and Kraus have spread the plugins to a variety of companies.

Hi Mwa mem,
thank you for this information . Under environment variables, it gives 2 boxes. One is for user variables and one is for system variables. Which one I have to use for the path?
And which path I have to gave in there and where - under value or under variables? At my System KPT is under C\program files (x86)\Adobe\Adobe Photoshop CS5\Plug-ins\KPT Collection
But how do I write this path and where? And what do I write under Variable and what under value?
Could you please give me this advanced information?

if you scroll down the system variables you'll find the path. Highlight it then click on modify. Don't forget to insert a semicolon before typing kpt's path. That's all. Or look at the reply and do it via a command line prompt.

EXACTLY RIGHT! I think the problem occurs with 64 bit. Thus the need for 2 machines. I run an image through Win 7, do the rendering and clean it up on a MacBook. My workflow usually consists of KPT consistently while 'creating' the image on a win pc. Then it goes through a NIK plugin process on a Mac.

Hi Cornelia,
I sincerely don't know what it means.
Didn't you forget the semicolon before the kpt path ? ;

From the image you posted must we understand that kpt effects work but not kpt collection ?
I think your best option is to reinstall kpt collection to the same location and see if it works.
on my computer all the kpt collection filters work allright

After the changing the path, KPT Effects works, but NOT the KPT Collection. I need very often the Fiber Optix of KPT Collection. I tried to install KPT Collection all on different places, but everytime the same error message like the screen before.

Hello mwa mem,
I've done this and it's the same. All is in the same folder. It works only KPT Effects but not KPT Collection. This was the reason I wrote here, that KPT Filters won't work and I can't connect Corel, because I can't join the Corel's User forum and on the site are no other contact possibility.

Hey Cornelia,
Did you correctly uninstall KPT collection before to install it again ?
try to uninstall kpt collection using "revo uninstaller" or something equivalent that cleans folders and registry after uninstall, then reinstall it again.
There's absolutely no reason that it works here and wouldn't do so with you. So it must be a mismatch in your registry due to multiple reinstallations.
Cheer up, it'll work eventually.

Hello,
This is Myriam De Clercq in Belgium. I want to confirm that adding KPT Collection's install folder to the "path" environment variable will indeed do the trick. I have Windows 7, and the 32-bit version of Adobe Photoshop CS6 will open the KPT filters correctly. Fabulous info from mwa mem. Thank you very much for sharing!
On Windows 7: Right-click on Computer, then Properties, then Advanced system settings, then Environment Variables, then in System variables, scroll down to the Path variable, higlight it, and click on Edit, ...

Does anyone know if this also works on the Mac side? I just upgraded OS's to 10.7 and am trying to get a few plugins to work that used to work in CS5...like Alien Skin Eye Candy. I tried going to the pref's and pointing directly to where they are installed, but they still don't show up. I guess I am just accepting that this is a difference between CS5 and CS6....but maybe there is some work-around...thought I'd take a chance and ask!

KPT plugins are a 32 bit plugin. Basically created for use on a Windows PC and older versions of PS. They have not been updated for some time since bought by Corel. Up until version CS2 and version 4 of Elements, the code has basically stayed the same with PS ( with a few exceptions to the brush engine ). Up until that time I ran all KPT versions and the most recent version of PS and Elements on a WIn PC with no problems. When Adobe released version 4 of Elements, I began having problems ONLY with version 3 of KPT. The work around for it was to undock the layer panel from the well and allow the rendering to occur. Otherwise, Elements 4 would lock up and prompted a Control+Alt+delete to close it. I have purchased every version of PS since then and have ran KPT in all versions on a Win PC with no problems. On My MacBook Pro, I only run the newest stuff ( it's my pride and joy ) ex: PSCS6 and NIK plugins. Mac's are 64 bit so KPT will not work on it. My advice to avid KPT users is to render on a PC and Icloud the files to the MAC. Corel will not update these plugins. I purchased the retail versions of them and also a bundle deal ( with AutoFX plugins ) from AutoFX.

Cornelia-It looks to me that you have created a separate folder labeled "KPT filters". Instead of doing this, when you install the plugins, simply pick the plugin folder in Adobe Photoshop CS5. EX: ( on a PC ) C/:Program files/adobe/adobe photoshop CS5/plugins. When you install, they will create their own file folder for each plugin ie; KPT 3, 5, 6, Effects.

Cornelia-
It appears that the message you are receiving has nothing to do with the KPT plugin or Photoshop. The error message is a system error message, meaning your register may be corrupt. A mCPSFilterSys.dll message pertains to the operating system. KPT plugins are highly CPU usage plugins and require generally more power than an average PC has. Try to uninstall the plugins through Add/Remove. Then follow these steps:
After removing them, run 'Regedit'. This is Windows registry editor. Not sure if you are familiar with it. Making changes to the registry could potentially screw up your machine badly. So proceed with caution.
After getting into Windows registry, navigate to HKEY_Current user and click on the arrow sign next to it to open it up and expose 'SOFTWARE'. Within software, you may see KPT listed in there. If so, delete it. Do this with each HKEY until all entries of KPT are deleted.
Reboot the machine. Open up Photoshop and check to see if the filters are gone.
Then manually delete the folders for them in C:/Program Files or wherever you previously installed.
This is to make sure that KPT is completely removed from the machine in both the registry and the OS.

Now, insert the install CD and 'Run as Administrator' for the KPT plugin and install it within C:/Program Files/Adobe/Adobe Photoshop CS5/Plugins. Do not create another folder within the Photoshop Plugins folder.

Well....I am spooked then. Only problems I've had is with the installer being so old, you have to click mouse until it kicks in to install and then occasionally replace the msvcrt10.dll in the applications.

Cornelia-
Did you check each HKEY? Mine was listed in LOCAL MACHINE/Programs. If so, then the only other 2 options I have are to try to install in Safe Mode OR disable background processes when installing such as Anti-virus. Which versions are you having particular trouble with?

Make sure you uninstall the application BEFORE deleting the key in HKEY LOCAL MACHINE/SOFTWARE. Then reboot and manually delete the application folder. Then try SAFE MODE install. Be sure to install by choosing "Run as Administrator". Basically what I am trying to do is Completely remove all traces of what might be a corrupt installer for the plugin from both the registry and the OS. The reboot hopefully aligns everything ( a Disc cleanup before install wouldn't hurt either ) so that when you attempt to put it on again, there will be no fragmented junk from the initial install attempt. If you don't mind telling me which version of the plugin you are having problems with. Is it ALL versions of KPT or just a specific one?

Thanks for your reply and trying to help me with my problem.
I have 2 collections KPT filters installed on my computer, there's KPT Effects KPT and Collections.
All filters from the KPT Effects collection work perfect. Some filters from the KPT Collection Collections also work fine, but the following filters have always shown the error message like the screen before and thus they can't be used.

For me is very bad, that Fiber Optix wouldn't be working, because I should use this very often.

I have Norton Symantex 360 Grad and I can't stop this, because this Anti Virus program is always on in the background. I would have to completely uninstall this Anti virus program and would therefore have no virus protection for this time.

For safety, I'll recheck all HKeys normally would appear in any section KPT, KPT since both programs are installed.
